squid3 is not built with helper /usr/lib/squid3/ext_time_quota_acl

Thank you for taking the time to report this bug and helping to make Ubuntu better. It seems that your bug report is not filed about a specific source package though, rather it is just filed against Ubuntu in general.

Fix for this has been added upstream in Debian package 3.5.14-1

any workaround ?

Workaround is to build Squid3 yourself from source package with the helper enabled.

This bug was fixed in the package squid3 - 3.5.23-1ubuntu1

---------------
squid3 (3.5.23-1ubuntu1) zesty; urgency=medium

  * Merge from Debian (LP: #1644538). Remaining changes:
    - Add additional dep8 tests.
    - Use snakeoil certificates.
    - Add an example refresh pattern for debs.
    - Add disabled by default AppArmor profile.
    - Revert "Set pidfile for systemd's sysv-generator" from Debian.
    - Drop wrong short-circuiting of various invocations; we always want to
      call the debhelper block.
    - Add missing Pre-Depends on adduser.
    - Enable autoreconf. This is no longer required for the security updates,
      but is needed for the seddery of test-suite/Makefile.am in
      d/t/upstream-test-suite.
  * Drop changes (adopted in Debian):
    - Run sarg-reports if present before rotating logs.
    - Add lsb-release build dep.
  * Drop changes that no longer make a functional difference in Ubuntu, but may
    still be relevant to send to Debian:
    - d/squid3.postinst: don't try to stop squid3 again.
    - d/squid3.postrm: don't rm -f conffiles in purge.
    - Drop squid3 dependencies on ${shlib:Depends} and lsb-base.
    - Drop creation of /etc/squid.
  * Drop unnecessary changes:
    - Add executable bits to d/squid.preinst.
  * Drop changes relating to the upgrade path from prior to Xenial, so no
    longer required:
    - /var/spool/squid3 upgrade path handling.
    - Conffile upgrade path handling.
    - Remove redundant version-guarded restart code from squid postinst.
    - Clean up apparmor links for usr.sbin.squid3 on upgrade.
    - Attempt to migrate /var/log/squid3 -> /var/log/squid on upgrade.
    - Add Breaks on older ufw to fix upgrade path.
    - Use Breaks instead of Conflicts. Instead, drop the Conflicts/Replaces
      entirely (see below).
  * Drop security fixes: all included in 3.5.23 upstream.
  * Drop Conflicts/Replaces of squid against squid3. In Ubuntu, the migration
    happened in Xenial, so no upgrade path still requires this code. This
    reduces upgrade ordering difficulty.
  * Fix failing autopkgtests:
    - Adjust Python module dependencies.
    - Correctly handle the squid3 -> squid rename.
    - Adjust seddery for upstream test squid binary location.
  * Drop dependency on init-system-helpers. This was introduced in LP 1432683.
    Since we no longer ship an upstart job, it is no longer required.
  * Correct attribution and add explanatory note in d/NEWS.debian.
